Question

a car is moving with velocity 40 meter per second acceleration is 2 metre second square and the time is 20 sec so find final velocity of a car​

Answer 1

GiveN :-

• Initial velocity of the car = 40 m/s

• Acceleration of the car = 2 m/s²

• Time = 20 s

To FinD :-

• Final velocity of the car

SolutioN :-

★ By using 1st law of motion :

$\large\longrightarrow \boxed{ \green{\bf V = u + at }} \: \: \: \: \: \: \: \\ \\\longrightarrow \sf V =40 + 2 \times 20 \\ \\\longrightarrow \sf V =40 + 40 \: \: \: \: \: \: \: \\\\\longrightarrow \underline{\boxed{ \blue{ \sf V =80 \: m/s}}} \: \: \: \: \: \:$
